As for connectivity, we can use the mouse directly by cable (it is the same one used to charge its battery), via Bluetooth or using the included USB dongle which allows transmission via radio frequency at 2.4 GHz Slipstream Wireless , which operates with a Polling Rate frequency of 1000 Hz (this means it has a response time of 1 ms).
Finally, it should be noted that the mouse promises up to 210 hours of battery life (using Bluetooth and with RGB disabled), although generally we will use it on a PC with RGB enabled and this time is reduced to 65 hours, according to the manufacturer.
The Corsair M75 is available today in black, white, and in wireless and wired versions. We will analyze the white Wireless version.
Unboxing and external analysis
Like practically all peripherals of this brand, the Corsair M75 Wireless is packaged in a rigid black and yellow cardboard box on the main side of which we can see an image of the product accompanied by its name and a brief description.
On the back we have a sketch indicating the most important parts of the device, with a description in several languages.
On the sides we find the name and brand, slogans, etc., except on one of them where three of its striking characteristics also stand out.
We open the box and the first thing we see is that the mouse is in the center, protected by a “bag” of recyclable paper with a sticker with the brand logo. On the left are the four replacement side buttons, while on the right we have the USB dongle and a section with a QR that takes us to the Corsair site and, below, the cable.
Beneath all this we also find the usual brochures that the law continues to require to be included in physical form, on warranty, safety and compliance.
Here you can see the rest of the accessories: the USB-C to USB-A cable braided in white nylon thread, a sticker with the Corsair logo, the USB dongle and the four button covers.
In the following gallery you can see all of these accessories a little closer, although there isn’t much to highlight other than that everything is white, just like the mouse.
Now let’s take a look at this Corsair M75 Wireless. As we said at the beginning, it has a symmetrical shape and is ergonomically designed for both right-handed and left-handed people, especially when you can change the thickness of the side buttons.
The main buttons are generously sized and the scroll wheel is rubberized and grooved to improve grip.
On the palm we have the manufacturer’s logo and two lines that go up to the middle of the body of the mouse, which will be the areas that will light up when it is turned on.
This is the right side, which comes by default with “bottom” button covers that leave them flush with the side of the mouse. Despite this, the buttons are not overridden and can still be pressed.
The left side is the same, except Corsair put the mouse model name on one of the sides. In this case, it comes with “tall” covers for the side buttons that stick out a bit… but don’t think too much about it.
Let’s get to the bottom, where we have quite a bit to say. For starters, the entire bottom area has a translucent plastic area that is also a lighting area. There are large sliding Teflon feet to move the mouse better, we have space to store the USB dongle, the sensor in the center and on either side of it two buttons: one to switch between off , Bluetooth and wireless, while the other is for sensitivity jumps.
After seeing the mouse from the outside, we’ll start testing it to see how it works.
Corsair M75 Wireless review
Before talking to you about how the mouse works, we will first show you some of its particularities, starting with the lighting. As you can see in the following image, when you are in a well-lit room, this is barely noticeable.
However, with the room in darkness or dim light, it looks pretty good.
In relatively normal lighting conditions, it looks pretty good.
Another special feature of this mouse are the side buttons, which come with spare parts of different thicknesses so that the buttons sit flush with the side or stick out a little.
It must be said that it is a little difficult to remove the buttons, in theory you have to press on one of the ends so that the opposite one goes up and remove it, but you have to insert your fingernail or a tool like a flathead screwdriver because otherwise it’s expensive.
Even with the thicker covers, we personally think that they protrude too little and, at least for us, they are uncomfortable firstly because they cause involuntary clicks, and secondly because when you want to press, it It’s hard to have the touch to do it.
Another curious thing about this mouse is how Corsair has defined how to change the resolution. Normally, mice usually have several resolution profiles that we can configure from the software (this one has it, of course), but in the Corsair M75 Wireless we can do it even without software. By default, the mouse is configured with a sensitivity of 1200 DPI, but by holding down the DPI change button and then pressing the buttons on the left side we can increase and decrease the DPI in steps of 50 at a time, and it will be saved in the internal system. mouse memory.
Now let’s give you our personal experience of using the mouse. To begin with, in terms of ergonomics, we found it very comfortable thanks to its symmetrical shape, most ideal for users who hold the mouse with a claw-like grip like us. Perhaps if you are used to an ergonomic mouse it will take a little adaptation, but in general it is very comfortable to use, partly also thanks to the fact that it is very light and also wireless.
In terms of performance, there’s not much to say: Corsair’s Marksman sensor performs very well on any surface and at any resolution level, giving you maximum precision in any situation, whether to work or play any type of game. We have already seen it in many other mice because it is the one that the manufacturer has used for a long time in all its mice, we are not going to so we won’t dwell much more on it.
As for autonomy, we use it with lighting activated and 50% brightness, and connected to the PC via the USB dongle with Slipstream, this is practically the condition in which the battery discharges the fastest. In these terms, a full charge of the Corsair M75 Wireless lasted us 63 hours until the mouse started to “complain”, causing the lighting to flash red. Corsair defines this warning as “low battery, recharge soon” and not yet as “critical battery, your mouse will turn off soon”, so we assume the warning appears when there is still at least 20% battery left, this which means that we could very likely have exceeded 70 hours of battery life.
Software: Corsair iCUE
As always, for the software to detect the new product, you need to make sure you have the new version installed. If this is the case, as soon as you connect the receiver and turn on the mouse, iCUE will detect it and offer to download the corresponding module.
Once done, you will need to restart iCUE and, after that, the mouse and its receiver will appear. On the mouse it tells you its connection type, the battery and the configured DPI.
Let’s see what the software offers us, although as you will see there is nothing different compared to other mice of the brand. In the first tab we have the key assignment, where we can configure what we want each button to do individually. In this section we have the same thing but “hardware”, in which we will basically write to the memory of the mouse so as not to have to depend on the software.
In the Lighting Effects section we can configure the RGB lighting of the device, although in this case we only have two areas to configure.
In the next section we can configure the DPI jumps.
In this sensor we also have a surface calibrator; We’ve never noticed a difference, but I suspect if they continue to incorporate it, it will be because there are people doing it.
Finally, we have the general options of the device, such as configuring the entry into sleep state, if we want to see the battery status in the taskbar, etc.
Conclusion and verdict
It’s not the lightest wireless mouse on the market nor the one that offers the best battery life, but it must be said that the Corsair M75 Wireless is an excellent mouse on both counts. At the same time, its Marksman sensor of up to 26,000 is as always precise and fast, fast thanks to Slipstream technology which gives you a latency of just 0.5 ms, making it an excellent choice for both competitive games for all types of uses you want. intend to give it away.
Now, it’s also a mouse that has some shadows in the face of so much light. The first of these is that we consider that the side buttons are too flat, which causes involuntary presses and quite the contrary, that when we want to press the button, we do not have enough touch to do it. We would have preferred buttons that stuck out a little more to avoid this.
Apart from that, as is almost always the case, the price seems a bit high: $129.99. It’s a good mouse, but we consider that it is not up to par with the competition and that around $100 would have been much more appropriate.
Generally speaking, it is a very comfortable mouse, responds very well, is highly configurable and also has a long battery life, which is why we can only give it our medal of gold and our recommendation for its performance.
